In the context of competition between individuals of the same species, the ability of some individuals to survive over others is primarily influenced by their adaptations to the environment, which can encompass several factors. Among the options provided:
-
Some do not need resources: This is not typically a factor, as all living organisms require some resources (like food, water, and shelter) for survival.
-
Some are not impacted by rapid changes: Some individuals may possess traits that allow them to endure environmental fluctuations better than others, but this is more associated with their adaptations rather than a standalone factor.
-
Some are better adapted: This option is the most relevant. Individuals that have traits better suited to their environment—such as those that can acquire food more effectively, evade predators, or withstand stressors—are more likely to survive and reproduce.
-
Some choose not to compete for resources: While some animals may exhibit behaviors that minimize direct competition (e.g., through niche differentiation), true non-competition is rare. Most will still be affected by resource availability.
In summary, the primary factor that allows some individuals to survive over others in a competitive environment is that "some are better adapted." Adaptation can involve physiological, behavioral, and morphological traits that improve an individual's fitness in their specific habitat.
